BAG HOLDER Filed June 19, 1946 za ze INVENTOR AT ORNEYS GLENN ASPINALL Patented June 21, 1949 UNITED STATES PATENT OFFICE BAG HOLDER Glenn Aspinall, Burlington, Wis.

Application June 19, 1946, Serial No. 677,772

4 Claims. 1

This invention appertains to bag holders and more particularly to a novel device for holding bags of different sizes in an upright position for filling.

One of the primary objects of my invention is to provide a bag holder embodying outwardly extending supporting arms provided with novel, depending bag engaging rollers, for facilitating the placing of the bag on and off of the arms and to prevent the slipping of the bag on the arms during the filling of the bag, the rollers also permitting the turning of a bag on the arms, so that the identifying label can be easily turned facing the operator.

Another salient object of the invention is to provide bag supporting rollers so designed that tangling of the bag mouth between the rollers and the supporting arms and the bearing axles for the rollers is prevented.

A further important object of the invention is to provide a pair of outwardly extending bag supporting arms rigidly fastened to swinging levers pivoted at a point remote from the arms on horizontal pivots, with a novel spring actuated linkage device, which normally functions to hold the arms and their carrying levers in opposite directions and away from one another.

Another further important object of the invention is to provide a supporting standard having slida'bly mounted thereon a elongated sleeve carrying the supporting arms and their levers and a cufi" adjustably mounted on the standard above the sleeve, with a spring connection between the cuff and sleeve, so that the weight of the bag and its contents during filling will cause sleeve to slide downwardly against the tension of said spring and permit the bag to rest on the ground, the adjustability of the cuff permitting bags of different heights to be associated with said holder.

A further object of the invention is to provide an antifriction roller mounting for the sleeve, whereby binding of the sleeve on the standard under the weight of the bag contents will be prevented.

A further important object of the invention is to provide novel means for detachably engaging the bag mouth at its inner side, so as to effectively hold the mouth bag open in such a manner that the filling of the bag by an operator will be facilitated, said means being so mounted thatthe same. can be swung out of the way when not in use.

A still further object of my invention is to provide an improved bag holder of the above character, which will be durable and eflicient in use, one that will be simple and easy to manufacture and one which can be placed upon the market at a reasonable cost.

With these and other. objects in view the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawing, in which drawing;

Figure 1 is a vertical central sectionalview through my improved bag holder taken substantially on the line l! of Figure 2 looking in the direction of the arrows, the view showing the bag partially filled and the sleeve pulled down under the weight of the contents of the bag.

Figure 2 is a front elevational view of my bag holder with parts thereof broken away and in section to illustrate structural detail.

Figure 3 is a transverse sectional view taken substantially on the line 33 of Figure 1 looking in the direction of the arrows.

Figure 4 is a detail horizontal sectional view taken on the line 4-4 of Figure 2 looking in the direction of the arrows illustrating the mounting of the swinging levers for supporting the arms.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views the letter H generally indicates my holder for a bag B during the filling thereof.

The bag B has merely been illustrated to show the use of my holder and the bag B can be of the character generally used for grain, feed, and the like.

The holder H includes a base 5 supporting an upright standard 6. The base 5 and the standard G can be formed from any preferred types of materials and in the examples shown in the drawing the baseand the standard are constructed of wood. The base 5 includes spaced parallel ground engaging feet or beams 1' and 8. These feet are rigidly connected by a ground engaging cross brace, 9. The standard is rigidly bolted to the cross brace 9, as at H).

Slidably mounted upon the standard 6 is an elongated sleeve II. This sleeve can also be formed of any preferred material. Above the sleeve is mounted an adjustable cuff l2 and the cuff can be secured to the standard in any selected position by means of a pin I3. The standard itself is provided with a row of equidistantly spaced openings I4. The pin I3 is placed through the cuff and into one of the selected openings. The cuff I2 supports the sleeve II and contractile coil springs I5 unite the sleeve with the cuff and these springs normally function to hold the sleeve up against the cuff. Obviously by placing the and at different heights on the standard the sleeve can be likewise positioned at different heights.

The opposite diagonal corners of the sleeve II rotatably carry antifriction rollers I6, for a purpose which will be later set forth. It is to be noted, however, that one roller is carried by the V front bottom edge of the sleeve and that the other roller is carried by the rear top edge of the sleeve and that these rollers engage the standard.

The sleeve II carries the bag supporting arms l! and I8 and these arms are secured at their rear ends to the upper ends of relatively broad swinging levers I9 and 20. The lower ends of the levers are received between front and rear brace bars 2! and 22. These brace bars are arranged in spaced parallel relation and are rigidly and firmly secured to the lower end of the sleeve at the front and rear faces thereof. Pivot shafts 22' extend through the brace bars and the lower ends of the levers and consequently the brace bars and the sleeve pivotally support the arms I1 and I8. The arms I! and I8 project forwardly from the sleeve and extend over the base 5. These arms carry novel bag supporting rollers 23.

The rollers 23 depend from the arms and the rollers can be of a substantially spool shape. Hence each roller includes a cylindrical body portion 24 and an upper and lower annular flange or rim 25. The lower rim or flange 25 of each roller can be provided with radially extending teeth or pins 26, the purpose of which will also later appear. The rollers are rotatably mounted on depending stub shafts 21 carried by the arms.

The arms are normally urged away from one another by a novel spring actuated linkage mechanism 28. The linkage mechanism 28 includes a pair of bottom swinging links 29, the outer ends of which are rockably mounted on the front terminals of the shafts 22. The inner ends of the links 29 are connected by means of hooks or the like 36, to a plate 3|. This plate in turn has connected therewith contractile coil springs 32. The upper ends of these springs are secured to a front plate 33 which is rigidly fastened to the sleeve. This plate extends above the sleeve, and the springs 32 normally pull up on the inner ends of the levers 29. The levers 29 are in turn operatively connected to the arm supporting levers I9 and 20 by links 34. These links at their lower ends are pivotally connected to the links 29 and are pivotally connected at their upper ends to the levers I9 and 20. Hence upward swinging movement of the links 29 forces the levers I9 and 26 and the arms I1 and I8 away from one another.

To limit the outward swinging movement of the arms I1 and I8 the rear ends of the arms are connected by a rope or the like 35.

In use of my bag holder the sleeve I2 is first adjusted to the desired height according to the size of the bag being filled after which the bag mouth is placed over the rollers 23 of one arm and this arm is pulled over by the bag toward the other arm and the bag mouth is then passed over the rollers of the other arm. The bag can be easily straightened on the rollers and the bag can be turned to correctly position the same thereon. The lower flanges of the rollers help in holding the bag on the rollers against accidental displacement and this is aided by the pins or teeth 26.

As the arms are normally urged away from one another, the bag will be held in an open position and hence the bag can be easily filled. As the bag is being filled the weight of the bag and its contents will gradually overcome the tension of the springs I5 and consequently the sleeve II will slide downwardly on the standard 6 until the bottom of the bag rests on the ground. This will, of course, take the weight of the bag and its contents off of the arms and cooperating parts. There is a tendency for the bag and its contents to tilt the sleeve II on the standard 6 and this tilting thrust is taken care of by the roller I 6 and these rollers permit the easy sliding of the sleeve on the standard.

After the bag has been filled, the same can be quickly and easily removed from the rollers by swinging in and down on the arms which will disengage the rollers from the bag. While the arms are still pressed inwardly, the arms can be moved up and out of the bag mouth.

In bags having relatively small mouths, the rear edge of the bag can be effectively pulled back between the arms to enlarge the mouth opening by means of hooks 36. These hooks 36 are pivotally mounted on the opposite sides of the upright plate 33. Normally, when the hooks are not in use, the same can be swung down in an out of the way position on each side of the upright plate 33 and in front of the sleeve II. When the hooks 36 are placed over the bag mouth the bag mouth will be pulled back toward the standard. Hence, the bag mouth is widened at a point at the rear thereof and away from the user, which facilitates the placing of a filling measure or scoop in the bag.

Changes in details may be made without departing from the spirit or scope of my invention but what I claim as new is:

1. A bag holder comprising an upright standard, an elongated sleeve slidably mounted on the standard, a supporting cuff adjustably secured to the standard above the sleeve, a spring connection between the sleeve and the cuff for normally holding the sleeve in a raised position, bag spreader and supporting arms carried by the sleeve, and antifriction rollers carried by the opposite diagonal corners of the sleeve for engaging the opposite faces of the standard.

2. In a bag holder, a support, a pair of outwardly extending bag spreader and supporting arms, levers rigidly secured to the rear ends of said arms, means rockably securing the levers at a point remote from said arms on horizontal pivots to said support, and a spring urged mechanism normally moving the arms away from one another including links rockably mounted at their outer ends to the support, spring means normally urging the inner ends of the links to a raised position, and connecting links pivotally secured to the first mentioned links and to the levers adjacent to the arms.

3. In a bag holder, a support, bag holding and spreading arms carried by the support, depending rollers carried by said arms for engaging in the bag mouth, said rollers being equidistantly spaced on said arms, and each of said rollers including a substantially cylindrical body portion and upper and lower annular flanges.
